Bollinger Bands Martingale MT4 EA

BBM (Bollinger Bands Martingale EA) is an automated trading system for MetaTrader 4 that combines Bollinger Bands signals with a configurable Martingale position-management system.

The EA is designed to automatically identify trading opportunities based on Bollinger Bands and manage subsequent positions according to your selected Martingale parameters.

How It Works

BBM monitors the Bollinger Bands and looks for trading opportunities based on the previous candle's closing price.

BUY Signal

A BUY trade is opened when the previous candle closes below the Lower Bollinger Band.

SELL Signal

A SELL trade is opened when the previous candle closes above the Upper Bollinger Band.

If the market moves against an open position, the optional Martingale logic can add another position after the configured price distance is reached.

The lot size of subsequent positions is increased according to the selected Martingale Multiplier.

The EA provides simple and direct external settings so you can customize the strategy.

Max Open Trades

Defines the maximum number of positions that the EA can open.

Fixed Lot Size

Defines the starting lot size for the initial trade.

Martingale Distance

Defines the distance in pips that price must move against the current position before the EA opens the next Martingale trade.

Martingale Multiplier

Defines the multiplier used to calculate the lot size of the next Martingale position.

For example, with a starting lot of 0.10 and a multiplier of 2.00, the next position can use 0.20 lots, followed by 0.40 lots, depending on the trading sequence.

Profit Pips

Defines the Take Profit distance in pips.

Bollinger Bands Period

Defines the period used to calculate the Bollinger Bands.

Bollinger Bands Deviation

Defines the standard-deviation setting used by the Bollinger Bands.

🎯 Custom Take Profit

Set your desired profit target directly in pips using the Profit Pips parameter.

The default parameters are:

• Fixed Lot Size: 0.10

• Martingale Distance: 20 pips

• Martingale Multiplier: 2.00

• Profit Pips: 10 pips

• Bollinger Bands Period: 20

These are the default settings and should not be considered guaranteed or optimized settings. Traders should test and optimize the parameters according to the symbol, broker conditions, timeframe, and personal risk tolerance.

This EA includes a Martingale trading mechanism, which can significantly increase market exposure as additional positions are opened.

Martingale strategies carry a high level of risk, particularly during strong and prolonged market movements against the trading position.

No trading strategy or Expert Advisor can guarantee profits.

Always perform your own backtests and forward tests on a demo account before using the EA with real funds.

Use responsible position sizing and understand the risks associated with Martingale trading before purchasing or using this Expert Advisor.
